September 1776, the first submarine " American Turtle " became operational by attacking the HMS Eagle in the harbor of New York.
American clockmaker Isaac Doolittle was instrumental in completing the egg-shaped "sub" by working on the flintlock mechanism and the timing device of the underwater mine.
